# Scientists Say Dark Matter Could Be Hiding Inside an Extra Dimension

## Extra Dimension

According to a team of researchers at the University of California, Riverside, an extra dimension in space-time could be hiding dark mater — the stuff that appears to make up 85 percent of the mass in the universe, yet remains undetectable by scientific equipment.

"We live in an ocean of dark matter, yet we know very little about what it could be,” said Flip Tanedo, assistant professor of physics and astronomy and the senior author of [the paper](<https://link.springer.com/article/10.1007/JHEP06(2021)008>) published in the *Journal of High Energy Physics*, in [a statement](<https://news.ucr.edu/articles/2021/06/02/new-dimension-quest-understand-dark-matter>).

"Our observed universe has three dimensions of space," he added. "We propose that there may be a fourth dimension that only the dark forces know about."

## Dark Matter Conundrum

Tanedo and his colleague's theory could finally allow us to explain its existence.

"It is one of the most vexing known unknowns in nature," Tanedo added. "We know it exists, but we do not know how to look for it or why it hasn’t shown up where we expected it."

Despite scientists' best efforts, dark matter has remained elusive. We still don't know what it is made of or why it exists in the first place. We also aren't able to observe it directly as it doesn't absorb, reflect or emit any kind of electromagnetic radiation.

## Dark Forces

But according to Tanedo and his team's theory, some invisible dark matter particles interact with other invisible particles in a way that causes these second particles to not behave like others — via an additional dimension.

"Over the past decade, physicists have come to appreciate that, in addition to dark matter, hidden dark forces may govern dark matter’s interactions," Tanedo said. "These could completely rewrite the rules for how one ought to look for dark matter."

"The extra dimension can explain why dark matter has hidden so well from our attempts to study it in a lab," he added.

## Author
I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida.
